What is CVE-2024-34581?
CVE-2024-34581 is a high-severity server-side request forgery vulnerability in n/a, published on 26 Jun 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The W3C XML Signature Syntax and Processing (XMLDsig) specification, starting with 1.0, was originally published with a "RetrievalMethod is a URI ... that may be used to obtain key and/or certificate information" statement and no accompanying information about SSRF risks, and this may have contributed to vulnerable implementations such as those discussed in CVE-2023-36661 and CVE-2024-21893. NOTE: this was mitigated in 1.1 and 2.0 via a directly referenced Best Practices document that calls on implementers to be wary of SSRF.
Weakness: CWE-918
